Hi all,

More of a database question here, my apologies:

I've been doing some reading on indexes but I thought I should get an
experienced persons input. My question is about "Over Indexing".
I have a MySQL MyISAM table that stores inventory transactions, in, out
etc. I store numeric fields that are primary indexes in other tables, 2
datetime fields and a qty field, Paul DuBois' MySQL book says that
anything used in a where clause or join clause is a candidate for an
index. It turns out that 7 out of eight fields fit this description,1
primary key, 4 smallints, and 2 are datetime fields. 
Should I use all these indexes or is this overkill?

Thanks for any input
